"Nusantara Language"

By the way:

https://en.wikipedia.org/wiki/Malay_orthography

The arrival of European colonial powers brought the Latin alphabet to the Malay Archipelago. As the Malay-speaking countries were divided between two colonial administrations (the Dutch and the British), two major different spelling orthographies were developed in the Dutch East Indies and British Malaya respectively, influenced by the orthographies of their respective colonial tongues.[citation needed] The Van Ophuijsen Spelling System used in the Dutch East Indies and later Indonesia was based on the Dutch alphabet. It was replaced by the simpler Republican Spelling System in 1947.

When are you going to get back to your pre-colonial writing systems?

Historically, various scripts such as Pallava, Kawi and Rencong or Surat Ulu were used to write Old Malay, until they were replaced by Jawi during Islamic missionary missions in Malay Archipelago.

Until you do, it does not deserve to be called "Nusantara language".
